SAFETY-STOP Foa MINE-cans.

Patented Maf. 1s, 1919.

Application Ied January 31, 1918. Serial No. 214,618.

To all whom t may concern y Be it known that I,\J0sEPH KLANsNIo, a.citizen ofthe United States,l and resident of the town of Black Diamond,county of King, and State of Washington7 have invented certain new anduseful Improvements in SafetyStops for Mine-Cars, of which thevfollowingis a specification.

' My invention Vrelatesto a safety stop attachment for mine cars andconsists of certain improvements over a device of the same charactershown in my previous PatentNo. 1,219,748', dated March 20, 1917;

The object of my present invention is to improve upon the constructionof the car therein shown, and particularly along the line of providingmeans by which the parts may be locked'in the position assumed when thecar body is raised, and also in the providing ofmechanisni whereby theswinging ofthe levers'upon which the'wheels are j ournaled, cannot takeplace in the opposite direction from that which is intended. Qtherobjects will be disclosed from a study of the specic-ati'on in this caseand the feal tures which Ik claim to be novel will be de.-

dropping down upon the rails when the fined by the claims terminatingsaid specification. i

In the accompanying Vdrawings I have shown my device embodied in theform of construction which I now prefer.

Figure 1 is a side elevation of a-car showing a Vportion of one sideandthe central partitions broken away, in order to better show theoperating mechanisms.

Fig. Qais av plan view .of my car showing` aportion of the body brokenaway in order to better showthe mechanism.

F'g. 3 is an end elevation of a car having myimprovement thereon, aportion of one end of the body being broken away. to show parts behindthe same. l f Y f In `the construction of cars shown in my previouspatent above referredto, no provision `was madeto prevent the car fromheavy strain, due to hauling upan incline, isre'moved. It would,therefore, be impos-V sible to operate said cars except on'inclineswhere the backward strain upon the haulage body of the, car raised.AShould the car, as shown in said patent, run upon a level stretch itwould immediately drop the car body upon the track- Y Furthermore, noprovision was made to in said patent, are provided with spurs-or dogs 20which project downward a sufficient distance to make certainA theirengagement with 'the ties or with other parts of the track structureinsuch manner as to stop the car and hold it, even if it be upon aconsiderable grade.

In some cases a` timber is employed eX- tenoling lengthwise of thetrack.l which timber would beplaced so as to be engaged by the spurs 20.These spurs are preferably secured to a plate 21 which is secured to theunder side of the beam 2. They are preferably made detachable so theymay be renewed in case one becomes broken Vor pulled out.

Car aXles 3 are journaled upon the car body in accordance with theconstruction shown in saidfpatent. Lever arms 4 are secured to theseaxles or shafts 3 at opposite ends and the track wheels 9 are journaledupon the swinging ends of these levers. Lever arms 5 are also secured tothese shafts` one upon each shaft.. These latter arms, instead of beingplaced at the outside of the car body, one at each side thereof, as wasdone in said patent, are placed at the center, one for each shaft 3.

Each of the'aXles is provided with vitsl lever 5, and these areconnected by a link 50, which link is also provided with means wherebythe haulage connection may be made therewith. A shield or casing 11,shaped to accommodate the wheels when the car body drops down, isprovided over each wheel, this being shaped so as to accommodate thewheels and the lever arms` upon which the wheels are mounted.

The mainhaulage connection is through a member which is. connected witha draft bar 6 secured to the frame of the car. The cable by which thecar is pulled, is connected with the eye 62 to which the member 60 issecured and to which also is secured a like vmember 61, this extendingto'V a connection with the forward end of the link 50. i

To accommodate the levers 5, and the parts connected therewith, asV V50and 61, a narrow compartment running lengthwise the car is formed by thetwc walls '12. 'This compartment may extend throughout the length of thecar and ordinarily would do so, but might be out short at the end oppo-vsitegthe haulage connection. This compartment should` preferably becovered on top and be open at the end where the cable 61 enters.Y` 1

It is evident that the strain upon the haulage cable communicatedthrough the connecting member 61, will act upon the longer lever 5, toswing the shorter lever 4, upon which the wheels are mounted, downwardvand backward, thus raising and maintaining the c-ar body in elevatedposition so long as this strain is continued. However,

. when this strain is released, the relative ansections.

gular` positions of the lever arms 4, as referred to a perpendicular,will cause the car body to dropl backward.

The strain communica-ted through this connecting member 61 is found tonot be suiiicient to maintain the car body raised when the car is on alevel track, or a track with a slight grade. It is, however, desirableto be able to operate these cars upon such level I,' therefore, providea locking link 8, which is pivoted to a bar 80 secured to one end of thecar body, which link- 8 is provided, at its freely swinging end, with ahook vwhich engages the forward end of'the link 50, or .with any othersuitable member which is connected withthe levers 5. When so engaged,the car body willsbemaintained inA raised position, even if the strainis entirely vremoved from the connecting mem- Asherein shown, I haveprovided a recess at 70 inthe outer vsides of the longitudinal beams 2and in the metal plate 21, which recess accommodates the lever arms 4upon which the wheels are journaled. The shoulder 7 at the rear end ofthis recess, is so placed that -it will engage the lever arm 4 andprevent it from swinging backward'v .farther than is desired.

Thisstop may, of course, be provided by.

'i i other means, but the one describedy I have found convenientandsatisfactory. By the use of a stoplocated in this manner itis impossiblefory the leversto swing too far in Y the "backward'direction Should ythewheel carrying levers swing forward tocsuch point that the car body willsettle uponthe trackway, .the carbody l can be automatically raised bypulling upon the haulage lines,Y as

y it could not if theleversA were toY swing Y' i backward or` in theopposite direction.
